x86: set CONFIG_USE_PRIVATE_LIBGCC to y
The motivation of this commit is to change CONFIG_USE_PRIVATE_LIBGCC
to a boolean macro so we can move it to Kconfig.
In the current implementation, there are two forms of syntax
for this macro:
- CONFIG_USE_PRIVATE_LIBGCC=y
- CONFIG_USE_PRIVATE_LIBGCC=path/to/private/libgcc
The latter is only used by x86 architecture.
With a little bit refactoring, it can be converted to the former.
